How to change scale of Y axis in Pi?

I wanted to change the scale on the Y axis of Pi.

For example, for IFCI, the Y axis is showing a precision of Rs 0.05 - which doesnt make sense as the min change in IFCI is Rs 0.1.

How can I change the Y axis scale?

You can use up and down arrows on charts and y-axis scale will change according to it.
